Quectel announces Dual-band High-precision Positioning module

Quectel Wireless Solutions Co., Ltd., the leading global supplier of cellular and GNSS modules, in association with STMicroelectronics, a global semiconductor leader that serves customers spanning a broad spectrum of industries, announced the release of the LG69T module, an automotive-grade dual-band high-precision GNSS module that integrates dead reckoning (DR) and real-time kinematic (RTK) technologies.

The new Quectel module, announced at 2019 Apsara Conference in Hangzhou, is designed to facilitate open sky positioning performance with an accuracy of up to 10-centimetres, which is currently the industry's most advanced positioning technology for the automotive market. LG69T will support next-generation precision positioning capabilities for smart vehicles and autonomous driving scenarios.

The Quectel LG69T GNSS module is based on ST's STA8100GA, the latest Automotive-grade dual frequency positioning chip with 80 tracking channels and 4 rapid-acquisition channels that are compatible with many constellations: GPS, BeiDou, Galileo, NAVIC/IRNSS and QZSS. It is an AEC-Q100 qualified dual-band (L1+L5) GNSS module that integrates multi-band RTK technology for centimeter-level accuracy.

The LG69T module's dead reckoning capabilities feature an integrated Inertial Measurement Unit (IMU) that provides continuous high-precision positioning. The LG69T supports corrections input for standard Radio Technical Commission for Maritime Services (RTCM) and centimetre-level navigation by using RTCM data from 3rd-local base stations. The module performs well under the highly challenging conditions of urban canyon environments.

“We are thrilled to collaborate with STMicroelectronics on our newest generation of high-precision positioning module. With this highly-integrated LG69T module, automakers and Tier 1 suppliers will no longer have to spend time selecting components, integrating hardware, adapting interfaces, and conducting tests and verifications, which will greatly cut their time-to-market and costs, and help them accelerate the deployment of autonomous driving to seize early opportunities,” said Min Wang, Automotive Product Line General Manager, Quectel.

“ST has strong experience and is the Global Automotive High Precise Positioning Technology and Market Leader. We are very proud to cooperate with leading Chinese smart driving high technology company,” said MH TEY, Greater China, South Asia and Korea Automotive Marketing & Application Head of Department STMicroelectronics. “Today, there is growing dependency on high-performance GNSS in automotive applications such as navigation, safety and autonomous driving. With this cooperation, we are very confident to become the market leader by providing cost-effective and unique best-in-class solution for autonomous vehicle.”

Engineering samples of Quectel's LG69T module will be offered to automakers and Tier 1 suppliers by the end of 2019, and the product will be commercially available around mid-2020 and is expected to be deployed in mass produced models as early as 2021.
